Method for improving transplanting survival rate of Machilus zhennan seedlings

By treating the roots with the use of temperature-sensitive root soothing agent and calcium peroxide in the soil, the problems of low transplant survival rate and poor growth caused by the root entanglement of the saplings of the sapling seedlings were solved, and the effect of improving the transplant survival rate and promoting growth was achieved.

AI Technical Summary

Technical Problem

The large seedlings in Zhennan containers inhibit oxygen circulation because of their entanglement and tight arrangement, which affects the root system's absorption of moisture and nutrients, resulting in a decrease in transplant survival rate and poor growth status.

Method used

By cutting the roots and mixing the soothing agent and calcium peroxide into the soil, the soothing agent is prepared from materials such as chitosan and β-glycerol sodium phosphate. It has temperature sensitivity and gelation characteristics, which promotes the growth of the root system to the soothing agent distribution area.

Benefits of technology

It improves the transplant survival rate of large seedlings of nanmu, promotes the absorption of moisture and nutrients of seedlings and the circulation of root oxygen after transplantation, and ensures good growth conditions.

Abstract

The invention discloses a method for improving the transplanting survival rate of phoebe zhennan seedlings, and belongs to the technical field of phoebe zhennan planting.The method comprises the steps of seed sand storage, sowing and seedling raising, root cutting treatment, transplanting and the like, phoebe zhennan is transplanted into a container after being sown and placed under a forest for shading and seedling raising, and roots are cut off for transplanting after the phoebe zhennan seedlings are cultivated into the seedlings; a root-relaxing agent is cooperatively applied in the transplanting process and can induce root systems of the machilus zhennan seedlings after root breaking to extend all around and grow well, so that the problem that the root systems of the machilus zhennan container seedlings of the multi-root-system tree species are coiled and wound is solved, then absorption of moisture and nutrients and respiratory metabolism after transplanting are inhibited, the transplanting survival rate of the machilus zhennan seedlings is reduced, and the survival rate of the machilus zhennan seedlings is increased. The later growth condition of the phoebe zhennan seedlings is influenced.
